Retatrutide 99.5% Purity — HomopeptideCertificate of Analysis · Independent third-party lab result
This COA was extracted from a community forum attachment. The original poster claimed a lab tested Homopeptide.com's Retatrutide, showing 99.548% purity via HPLC + MS and a quantity of 20.10mg (0.5% over label). The test is recent (3-6 months old). However, the lab's signature is not directly verifiable from this source, and the image has passed through at least one re-share, creating a chain-of-custody gap.
